Spectral approaches are ways of isolating molecules. Molecules of natural origin are those that are found in nature and have not been modified.
One scientific model is PSM which theories that the origin of life began from molecules found in the ocean. Another scientific model for the origin of life is BM which believes chemicals surfaced on top of the water. Both theories are hard to prove.
The current theory of evolution by natural selection was introduced formally by Charles Darwin, in his work "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life", first published in 1859.
The only scientific consensus on "the origin of life" is that it arose of organic molecules. Charles Darwin is often cited for this theory but his theory of evolution only dealt with the changes within existing organisms. There isn't really a single scientist one can name and give credit to for abiogenesis.
